External Control

7About the external control

This monitor has three external control terminals.

• MAKE/TRIG. terminal : The following external control systems are available.

(1) MAKE (make contact system): Controls the function by short-circuiting the corresponding pin terminal to the GND pin terminal, or disconnecting (opening) it (☞ the right).

(2) TRIGGER (trigger system) : Controls the function by inputting the pulse signal instantaneously to the

	corresponding pin terminal (☞ the right).
• RS-232C terminal	: Controls the monitor with RS-232C system. (☞ “Using the serial communication”
	on page 15)
• RS-485 terminals	: Controls the monitor with RS-485 system. (☞ “Using the serial communication” on
	page 15)

Set the following items of “REMOTE SETTING” in set-up menu according to the external control terminal and control system you use (☞ page 13).

7Using the MAKE/TRIGGER system

MAKE/TRIG. terminal is configured as follows. You can assign a function to each pin terminal in “REMOTE SETTING” (☞ “PORT F1” – “PORT F6” on page 13).

	Pin No.	Pin name	Pin No.	Pin name
This is a female	1	PORT F1	5	PORT F5
	2	PORT F2	6	PORT F6
terminal.
	3	PORT F3	7	External control*3
	4	PORT F4	8	GND

*3 The external control (the 7th pin terminal) must be controlled by the MAKE (make contact) system.

To assign the functions to the pin terminals

For the operation procedure, see page 7.

1 Select “REMOTE SETTING” on the set-up menu.

2 Set “PARALLEL TYPE” to “SET.”

3 Select a pin name (“PORT F1” – “PORT F6”) which you want to assign a function to, then select the function you want to assign.

• For selectable functions, see the tables below.

communication RS-232C RS232C*1 —

*1 On the monitor connected to the personal computer etc, select the terminal the equipment actually connected to. On the other monitors, select “RS485.”

NOTE

•Control priority is as follows.

MAKE > TRIGGER, serial communication, and buttons on the monitor

•You can use the external control even when “CONTROL LOCK” is set to “ON” (☞ page 13).

<MAKE/TRIGGER system>

You can control the monitor by a personal computer or dedicated controller*2. For the details, see the right.

*2 The controller is not commercially available. Consult your dealer if you need it.

*6 Selects which functions in “AREA MARKER” are activated, “R-” items or non-“R-” items (☞ page 10).

*7 Displays the information shown when INPUT SELECT button of the current input is pressed (☞ “About the Status Display” on page 7). While controlling with MAKE (make contact) system, the information is displayed only at the moment of short-circuiting.

NOTE

•You cannot assign the same function to different pin terminals.

•The TRIGGER system switches each function by short-circuiting the pin terminal for about 1 second and opening it.
